7 Claims.

My invention relates to thread winding machines, and has for its object to provide a novel and improved machine for winding a thread cop of the type having one end of the thread mass convex and the other end concave. 1

The several features of the invention will be readily understood from the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a portion of a machine embodying the features of the invention in their preferred "form;

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is a sectional view,

on the line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. '3; and

Fig. 5 is a front elevation of a machine illustrated in Fig. 1.

The machine illustrated in the drawings, is particularly adapted for use in winding the thread cop shrown in Fig. 1 which comprises a conical core or tube 2 and a base 4 having its upper or inner surface convex. The thread is crosswound on the core in such manner that the successive layers are progressively displaced longitudinally of the tube so as to cause the inner or lower ends of the layers to be laid adjacent the convex surface of the base 4, the other end of the layers being convex. l The machine is of the type of the one illustrated and described in the patent to George N. Taylor, Winding machine, No. 1,258,824, dated March 12, 1918. The machine is provided with a winding spindle 3, a cop tube holder 5 carried thereby and mounted to slide longitudinally and a thread guide 6 for traversing the thread longitudinally of the cop tube 2. The spindle is driven from a suitable source of power through a pulley 8 which is connected with the spindle through the usual clutching device (not shown). The thread guide 6 is actuated through connection with a cam ID that is driven from the main drive shaft on which pulley B is mounted, through belt l2 which passes over pulleys M.

The machine is further provided with a thread measuring device which acts automatically to stop the winding operation of the machine when a predetermined length of thread has been wound on the cop tube. The thread as it passes to the thread guide 6, passes beneath the usual drop wire I], around a wheel l6 and beneath a fixed guide 18. The drop 55 which is shown, is connected as customary with taken substantially portion of the wire ll, a portion only of the usual stopping devices of the machine to stop the machine upon breaking of the thread.

During the winding operation, the cop holder is shifted axially in one direction so as to cause the layers of thread to be progressively displaced, as above described. In the machine of said Taylor patent, such shifting movement of the cop holder is effected through connection with the thread guide. As the layers of thread are built up on the cop holder and the thread guide is thereby caused to be moved outwardly, it acts through said connection to effect the desired shifting movement of the cop holder. In the winding of glossy or silk finished thread, on a more or less steeply conica1 cop, owing to the increased pressure that the thread guide is caused to place on the mass of thread being wound in order for the connecting mechanism to effect shifting movement of the cop holder, there is danger of the thread guide causing the thread to slough off and the mass of thread to bulge at its outer end which of course is objectionable.

In accordance with the present invention means are provided for effecting the desired shifting movement of the cop holder independently of the thread guide. As shown, this mechanism is actuated through connection with the thread measuring device of the machine. This measuring device may be driven by any suitable means, but

preferably is driven from the wheel l6 which in turn is driven by thethread passing around the wheel. The shaft of the thread measuring wheel carries a worm 20 that engages a worm wheel 22 secured on the shaft 24. This shaft 24 carries a worm which through a worm wheel 26 and worm 28 drives a worm wheel 30 loosely mounted on a shaft 32. The worm wheel 30 is normally secured to the shaft 32 through a friction clutching device, comprising a friction disk 34 secured to the shaft 32 and a friction disk 36 keyed to but slidable on the shaft 32, the two friction disks engaging opposite sides of the worm wheel 30. The disk 36 is pressed against the wheel 30 so as to cause said wheel to be frictionally secured to the shaft by means of a spring 38 coiled about a boss on the disk and a boss on a disk 40 pinned to the shaft 32. A hand-wheel I2 is secured on one end of the shaft 32 and carries a handle 4 that is normally pressed outwardly by means of a spring 46 so as to cause the inner end of a stem 48 secured thereto to be positioned to cleara stop member 50 on the casing of the measuring device upon rotating the hand-wheel, the construction allowingthe handle to be pressed inwardly when desired to enable the end of the stem 48 to engage the side of said stop member 50. I

The other end of the shaft 32 carries a knockoff cam 52. A pin 54 mounted to slide vertically is held in engagement with the surface of this cam by an arm 56 having one end pivoted on a pin 58 on the casing of the measuring device, and having its other end pivotally connected with the upper end of a rod Gil. When the point 62 of the cam passes the lower end of the pin 54, the rod 60 is permitted to drop down and strike the drop wire I! to stop the winding operation of the machine.

The shaft 32 also carries a cam 64 which has a cam groove that receives a cam roll 66 on the end of a cam lever 68. This lever is pivoted on a pin or bolt 70 that is carried on one end of a link 12 having its other end secured on a pivot pin or bolt 74. The bolt 10 extends through an elongated slot in the lever 68 and the bolt 14 extends through an elongated slot in a bracket E6 on the machine frame. The lower end of this lever is bifurcated and the ends of the forked arms are 'pivotally connected by pins 18 with a ring or collar that is mounted on the inner end of the cop tube holder, the collar being connected with the cop tube holder through ball-bearings 82.

The speed reduction between the shaft of the measuring wheel I 6 and the cam shaft 32 may be such that during the winding of approximately six thousand yards of thread on the cop tube, the shaft makes approximately four-fifths of one revolution. During the rotation of the shaft 32 the cam 64 acts through the cam lever 68 to shift the cop-holder outwardly in timed relation to the winding of the thread so as to cause the successive layers to be progressively displaced as above described. At the completion of the winding of the predetermined yardage of thread, the point 62 of the cam 52 passes the lower end of the cam pin 54, causing the rod 6!! to act to stop the rotation of the spindle as above described. The completely wound cop may then be removed from the cop-holder and the next cop tube to be wound applied. Before again starting the machine in operation the hand-wheel 42 is turned in a clock- Wise direction, so as to return the inner end of the stem A8 of the handle adjacent one of the stops it], thus returning the cam 64, the knockoif cam 52 and the cop-holder to their initial positions ready for the next winding operation, the knock-off rod 60 being raised to its initital position by the cam 52. The friction clutch connection between the worm wheel 30 and the shaft 32 allows such turning of the hand wheel independently of the reducing gears.

By varying the angular positions of the knockoff cam 52 with relation to the cam 64 the yardage may be varied as desired.

The shifting movement of the cop-holder may be varied with relation to the rate of travel of the thread and the rotation of the spindle, by adjusting the pivot bolt 10 in the elongated slot in the lever 68, and adjusting the pivot bolt 14 in the elongated slot in the brackets 16. Such adjustment of the shifting movement of the cop-holder may be required for different sizes of thread, and also for thread cops having the inner convex surfaces of their bases at different angles.

My improved mechanism is simple in construction and efiicient in operation, and may be easily applied to theusual Universal winder and similar machines.

It will be apparent that instead of shifting the thread cop with relation to the path of the reciprocating traverse of the thread guide, the desired result may be secured by shifting the thread guide with respect to its reciprocating traverse in a direction longitudinally of the thread cop. It will also be apparent to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.
